A method for detecting an object in a motor vehicle environment uses a detection means which scans the environment at predetermined angular increments &#x3c6;i+&#x2212;&#x3c6;i (i=1,2, . . ., N). When sensing a reflection signal of the object at an angle &#x3c6;i, the angular increments are refined in the angular range between the adjacent angles &#x3c6;i&#x2212;1 and &#x3c6;i+1 as a function of signal propagation times ti&#x2212;1, ti and ti+1 of the reflection signals sensed at the angles &#x3c6;i&#x2212;1, &#x3c6;i and &#x3c6;i+1.

Method and apparatus for detecting an object in a motor vehicle environment

A vehicle-useful, high-resolution 3D-detection of the environment of a street vehicle with environment scanning sensors is not possible today. Depending on application the first commercially available vehicle integrated systems may be a comprise between resolution of the sensors and size of the sampled area. With the inventive two dimensional distance resolution sensor device it becomes possible, in contrast to those which are known, to produce a system which, installed in a street vehicle, detects and preferably processes complex dynamics scenarios such for example street traffic, from the prospective of the active dynamic moving vehicle. Therein a three dimensional image of the environment is produced using a distance sensor, which produces a two dimensional distance profile (depth profile), and on the other hand, using a data processing and a storage unit, which process and store sequential distance profiles and sequence a series of distance profiles into the three dimensional image of the environment.
